Manufacturer Narrative

Cmp-(b)(4).Complaint sample was evaluated and the reported event was confirmed.Device history record (dhr) was reviewed and no discrepancies related to the event were found.Root cause was unable to be determined.An arcos 3.5mm hex drive, part 31-301852 from lot zb121001, was returned and evaluated against the complaint.Visual inspection confirmed the hex tip to be fractured from the driver.The tip remains lodged inside the cone body, however the location prevents the tip from being visible.Wear rings are present around the distal end of the shaft near the fracture.Device has a potential field age of approximately 8 years.The returned device was sent to sem for further analysis.The driver tip fractured angularly to the long axis as detailed.Fracture surface artifacts suggest a torsional overload fracture.Xrf analysis found the hex driver material to be consistent with 430/440 stainless steel alloy.If any further information is found which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.
